Qmetrics’ 3D Medical Models Assisting Pediatric Cancer Patients

Children and adolescents aren’t immune from orthopedic disease and injury. Highly active and energetic, children do suffer sports injuries, and their cases can sometimes present challenges. One benefit of Qmetrics ability to develop 3D images and anatomic models from MR scans is that it can avoid radiation exposure in pediatric patients associated with CT scans. Additionally, the rich soft-tissue data found in MRI images may provide physicians with a better understanding of injury or disease extent.

Sample 3D Model from MRI

The Qmetrics team is honored to partner with one of its clients to support development of custom orthopedic implants for young cancer patients. Qmetrics provided an accurate 3D model of the patient’s anatomy, enabling the client’s engineers to design and fabricate an implant customized for the patient. This application of advanced image analysis helps the patients’ physician pursue options designed to preserve the child’s limb while treating the cancer.

“Qmetrics is proud to be working with our orthopedic partners to help cancer patients receive the best possible treatment options,” commented Edward Schreyer, CEO, Qmetrics. “We realize the importance of making our proprietary technology available in a clinical setting so treating physicians can benefit from the rich information in medical image data to make better care decisions. We would be happy to work with clinicians facing these challenges, and facilitating conversations with our partners to help develop custom solutions for their pediatric and other patients.”

The Knee Joint
The knee joint is an incredibly strong, intricate and complex part of human anatomy. It is the largest joint in the human body. Its role is to provide strength, support, and flexibility while standing, walking, and bending down.
The knee is a hinge joint, meaning it allows the leg to extend and bend in one direction. The knee is considered a mobile, or pivotal hinge joint as it also allows minimal medial and lateral rotation.
To allow the necessary movements and provide a great deal of strength and structure, there are many structures in the knee joint that need to function well:
• Knee bones. The bones must maintain their strength and smooth surface in order to move easily against each other. Development of boney growths, called osteophytes or bone spurs, may impede this function and cause pain.
• Knee cartilage. The cartilage must be smooth and strong to allow the bones to move against each other, acting as the hinge in the joint, without too much friction.
• Knee muscles. The muscles - which include the quadriceps muscles in front of the knee and the hamstrings on the back of the knee - must be both flexible to allow normal range of motion and strong to adequately support the knee joint.
• Knee ligaments and tendons. The multiple ligaments and tendons around the knee must be strong to bind the knee joint together and encapsulate it in a tough but flexible structure.
Problems occur when any of these parts of the knee joint start to degenerate or are in some way damaged or irritated.
